The Lowdown
Alright, let’s get into it. The next couple of weeks have some real pulse to them, especially if you’re chasing that bigger, groundswell juice. The water is sitting right around 80° which is pretty much what you’d expect for this time of year, nothing crazy going on there.
We’re looking at a solid run of surf starting Sunday, August 9th. It kicks off with a clean 8ft SSW groundswell, with a long 16-second period. The wind is a light cross-off, which is going to keep things looking sexy. The energy is strong, reading 2550, and the wave comment is spot on for experienced surfers. This is where you want to be.
The next couple of days, Monday the 10th and Tuesday the 11th, see the swell building. Monday morning is a bit smaller at 6ft, but the afternoon jumps up to 8ft with an even longer 18-second period and that energy jumps to 3844. That’s a serious step up. But Tuesday, the 11th, is where it gets critical. The swell hits 10ft with a 17-second period, and the energy is pumping hard at 4447. The wind is still favorable, but the call is clear: this is too big for this break. It’s expert-only territory, and even then, it’s going to be on the edge. If you’re not 100% confident, give it a miss.
After that peak, it settles back into a really fun, manageable zone. From Wednesday the 12th through to Sunday the 16th, we’ve got consistent 5ft to 7ft SSW swell, with periods mostly in that juicy 14-17 second range. The winds are light and cross-off, mostly from the SE. Energy readings are strong, in the 1776 to 2722 range. This is the sweet spot for the intermediate crew. The break is consistent, so there’ll be waves all day. It’s going to be clean, and the light winds are going to make it feel like a lake out there. This is your window for the best overall quality, especially Monday afternoon and the weekend mornings.
The following week, things back off a touch. Monday the 17th is still fun at 6ft, but the energy drops. Then we get a proper reset on Tuesday the 18th, with a new, longer-period SW swell at 21 seconds, but smaller at 3ft to 5ft. That’s a sign of a new groundswell filling in. Then, hold onto your board, because Wednesday the 19th and Thursday the 20th look like another big pulse. We’re talking 8ft to 10ft SW swell again, with strong energy readings in the 3785 to 5515 range. Just like the previous Tuesday, this is going to be too big for the spot. The wind is cross-off and clean, but the size will be the limiting factor. Only the experts should even be looking at it.
After that, it fades back down to a more manageable 6ft to 8ft range for the rest of the run, with light winds and clean conditions. The period drops back to 14-16 seconds, which is still good. The energy is moderate to strong, but it’s not going to have that same bite to it. The last couple of days, the 23rd and 24th, are still surfable but the energy is waning. It’s a good time to get the longboard out or just enjoy the cleaner, smaller conditions.
Standouts: The best overall conditions for the average competent surfer are going to be the Monday afternoon session on the 10th, and then the morning sessions from the 13th through the 16th. The biggest, most powerful, and cleanest swell windows on the 11th and the 19th-20th are for experts only, as the size is just too much for this reef.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
